If left untreated, this common disorder can be life- threatening. Sleep Apnea Symptoms Frequent silences during sleep due to breaks in breathing (apnea) Choking or gasping during sleep to get air into the lungs Loud snoring Sudden awakenings to restart breathing or waking up in a sweat Daytime sleepiness and feeling unrefreshed by a night’s sleep, including falling asleep at inappropriate times What Happens? When you stop breathing during sleep due to sleep apnea, the balance of oxygen and carbon dioxide in the blood is upset. The brain signals you to wake up so the muscles of the tongue and throat can increase the size of the airway. These waking episodes are necessary to restart breathing (and to save your life). You may not remember, but these episodes disrupt your sleep and cause daytime exhaustion. Two Types of Sleep Apnea Obstructive Sleep Apnea (OSA) OSA is the most common type of sleep apnea. It is caused by a breathing obstruction, which stops the air flow in the nose and mouth. Central Sleep Apnea (CSA) Central sleep apnea (CSA), less common than OSA, is a central nervous system disorder that occurs when the brain signal telling the body to breathe is delayed. CSA can be caused by disease or injury involving the brainstem, such as a stroke, a brain tumor, a viral brain infection, or a chronic respiratory disease. People with CSA seldom snore. Effects of Sleep Apnea Sleep apnea has serious health consequences and can even be life-threatening. The main effects of sleep apnea are: sleep deprivation oxygen deprivation Sleep Deprivation Frequent waking causes fitful sleep and prohibits therapeutic rest. Apnea episodes have side effects like excessive sweating and a frequent need to urinate which disrupt sleep. Awake feeling like you have not slept or have difficulty staying awake during the day. Some trickle-down effects include a compromised immune system, poor mental and emotional health, and irritability. Oxygen Deprivation When you stop breathing, your brain does not get enough oxygen. Serious problems can result from the oxygen deprivation of sleep apnea, including heart disease, high blood pressure, sexual dysfunction, and learning/memory problems. Depression and Sleep Apnea Approximately 1 in 5 people who suffer from depression also suffer from sleep apnea People with sleep apnea are 5 times more likely to become depressed. Sleep Apnea may worsen existing depression. While it is not clear whether the apnea causes the depression or vice-versa, studies show that by treating sleep apnea symptoms, depression may be alleviated in some people. Self-help Treatment for Mild Sleep Apnea Lose weight: Overweight individuals who lose even 10% of their weight can reduce sleep apnea and improve sleep quality. Stop using alcohol, tobacco, and sedatives: avoid anything that relaxes the muscles of the throat and encourages snoring. Sleep on your side: Special pillows or remedies that encourage side-sleeping might help people who only experience sleep apnea when they sleep on their back. Elevate the head of your bed 4 to 6 inches: This can alleviate snoring and make breathing easier. Maintain regular sleep hours: create a routine and stick to it. Use a nasal dilator, nasal congestion strips, or saline nasal spray: these will help to open nasal passages. Chronic Fatigue Syndrome (CFS) Chronic Fatigue Syndrome (CFS) is a condition of prolonged and severe tiredness or weariness (fatigue) that is not relieved by rest and is not caused directly by other conditions. To be diagnosed with this condition, your tiredness must be severe enough to decrease your ability to participate in ordinary activities by 50%. CFS Diagnosis Fatigue or tiredness, never experienced to this extent before (new onset), lasting at least 6 months and not relieved by bed rest Fatigue severe enough to restrict activity (serious fatigue develops with less than one-half of the exertion compared to before the illness) There are no specific tests to confirm the diagnosis of CFS, though a variety of tests are usually done to exclude other possible causes of the symptoms. CFS Symptoms Fatigue lasting more than 24 hours after normal exertion Feeling unrefreshed after adequate sleep Forgetfulness or other similar symptoms including difficulty concentrating, confusion, or irritability Headaches, different from previous headaches in quality, severity, or pattern Joint pain, often moving from joint to joint Lymph node tenderness in the neck or armpit Mild fever (101 degrees F or less) Muscle aches Unexplained muscle weakness Sore throat 30 Medications Become a label reader! Any medication that identifies a side effect of drowsiness – heed the warning! Modify dosage schedule so drowsiness happens at night when you are not going to be driving a school bus Ask your physician is there is an alternative medication that does not cause drowsiness Beware over the counter medications as well – read the label carefully 31 When You Experience Warning Signs Stop driving immediately Pull over in a safe place Walk around the vehicle and take in fresh air Nap for 10-20 minutes if possible If warning signs persist - Notify your dispatch What You Can Do to Prevent 32 Drowsy Driving… Get at least 8 hours sleep daily Avoid driving during the times you are normally sleeping Avoid medications whose side-effect is drowsiness Keep temperatures in driver’s compartment cool During long trips take a break every 2 hours (or sooner if warning signs are present) 33 Awareness if Key Awareness of the risks and your body’s reaction to sleep deprivation is key Our society spins at a faster pace than ever before Sleep deprivation becomes a way of life But for a school bus driver, there is so much more riding on your good nights sleep Make it Routine… 34 Create good sleep routines and follow them When you are fatigued – choose not to drive If you experience the warning signs while driving you bus – pull over and notify dispatch No matter what you think the consequences will be – they will be less than if you cause a crash and kill a child Driving when you are sleepy or tired is risking your life and the lives of your students 35 Thank you!.

As such, PSG is an expensive and cumbersome procedure, particularly for use in the home environment. Actigraphy devices are a common practical alternative Published date: Nov 06, 2017 that can be used in the home environment, but they often underestimate sleep latency. For these reasons, it is difficult to accurately measure sleep latency outside of the sleep laboratory setting. *Corresponding author This problem has led to the revival of active behavioural devices for measuring sleep latency. Thim is a Hannah Scott, School of Psychology, small active behavioural device that uses behavioural responses to stimuli to measure the onset of sleep.

  • The Science of Sleep
    In order to have efficient and normal functioning of all systems in the body adequate and restorative sleep must be obtained. Mental and physical health is directly affected by an individual’s sleep patterns with poor sleep resulting in a reduced ability to ward off and cope with sickness, a reduced capacity for cellular healing, repair and replacement. This can directly result in altered body system functions and processes that can adversely affect overall wellbeing, particularly in those with autoimmune and other inflammatory conditions. Lack of sleep can also lead to changes in; moods, anxiety, irritability, cognitive function and concentration. Loss of adequate and restorative sleep has also been associated with reduced balance and hand eye co-ordination with the potential for increased injury and decreased capacity to complete work tasks. Sleep is considered to be a dynamic process which involves continuing brain activity which acts to produce and release hormones and proteins essential for organ system regulation as well as growth and tissue repair. The attainment of adequate sleep encourages the maintenance of emotional and social functioning while awake by giving a rest during sleep to the parts of the brain that control emotions and social interactions. Brain chemicals and hormones such as serotonin, adrenaline, melatonin and cortisol are directly involved with many signalling pathways and organ functioning in the human body. These chemicals are involved in nerve signalling processes and play an important part in controlling the sleep and wakening processes by stimulating different parts of the brain and inhibiting other parts of the brain to either promote sleep or keep a person awake.

  • Eating Behaviours and Attitudes in Narcolepsy and Their Association with Sleepiness and Mood
    Eating Behaviours and Attitudes in Narcolepsy and their Association with Sleepiness and Mood Danielle Marie Gatti, BA (Psych. Hons) School of Psychology, Faculty of Arts, Education and Human Development, Victoria University Submitted in partial fulfilment of the requirements of the degree of Doctor of Psychology (Clinical Psychology) (2012) Eating, Sleepiness and Mood in Narcolepsy ii Abstract A number of studies have found maladaptive eating behaviours and attitudes in individuals with narcolepsy, however, few studies have comprehensively investigated possible reasons (other than hypocretin deficiency) for these findings. The aim was to investigate the eating behaviours and attitudes of individuals with narcolepsy. The sample consisted of 73 individuals with narcolepsy and 74 controls. Measures used were the Bulimia Test, Depression Anxiety Stress Scale and Epworth Sleepiness Scale, a one day Food and Drink Intake Diary, a newly developed Meal and Snack Timing Questionnaire and an adapted Meal Choice Questionnaire and Snack and Drink Choice Questionnaire. Results showed that individuals with narcolepsy consumed significantly more snacks and drinks than controls. Controls were more concerned about the impact of snack and drink choice on their weight. Individuals with narcolepsy were more likely to binge eat than controls. Individuals with narcolepsy rated the importance of timing food intake with convenience of sleepiness more highly than controls. Individuals with narcolepsy had significantly higher levels of depression, anxiety and stress than controls. Individuals with narcolepsy with moderate to severe levels of anxiety and stress scored significantly higher on the binge factor than those with normal to mild levels of anxiety and stress. A hypothesis is developed suggesting that two opposing frameworks may be operating in narcolepsy, one of a purposeful eating behaviour and another of uncontrolled eating behaviour.

  • Take a Break: Increased Productivity Thanks to Axbo Power Napping
    Take a break: increased productivity thanks to aXbo power napping Our society demands that we produce top performance and results quickly and consistently – all throughout the day. But if we were to listen to our natural biorhythms, this would be an impossible feat. As of November 1st, the aXbo sleep phase alarm clock is equipped with a new function, "PowerNap," for brief midday naps. Power naps have a rejuvenating effect. We spoke with Dr. Georg Dorffner, university professor and managing director of the Siesta Group Schlafanalyse, about power napping, the effects of power napping and the studies carried out on the topic. Vienna, 31 October 2007 – The lights are dimmed, telephone calls are re-routed, and no meetings are scheduled: imagine reclining in your chair and taking a short relaxing break – right in the middle of the working day, and without a guilty conscience. This is the dream of many a hard worker, yet our achievement-oriented society demands from us that we work twelve hours a day or more, every day, and remain highly concentrated and in best form all day long. However, sleep research findings show that we experience a decrease in performance levels around noon. Sleep researcher Dr. Jürgen Zulley actually discovered this phenomenon over 20 years ago when he arranged for 450 volunteers to spend 4 weeks in a subterranean bunker. Without daylight or clocks, the test candidates soon lost all feeling for the time of day. "The test persons usually took a nap of around half an hour around noon under the assumption that it was already evening.

  • The Effect of Power Napping on Performance
    Utrecht University Applied Cognitive Psychology Master thesis The effect of power napping on performance Name: Luke Crooymans Student number: 0494992 Date: 15-08-2011 Philips Research High Tech Campus, 5656 AE, Eindhoven, the Netherlands Utrecht University: Stella Donker & Maarten van der Smagt Philips Research: Roy Raymann & Els Møst 1 Contents: Page: Abstract: 3 Introduction 4 Methods 8 Participants 8 Design & Procedure 8 Materials 10 Statistical procedure 13 Results 16 Sleep data 16 Subjective measures 19 Performance measures 21 Discussion 26 Acknowledgements 29 References 30 Appendix 33 2 Abstract Introduction Daytime (power) napping has been demonstrated to counteract feelings of fatigue and decreases in cognitive performance during the day. However, the duration and the composition of daytime naps are decisive for their restorative power. Short naps may be too brief to relieve sleep pressure, boost alertness and cognitive performance. Longer naps have an increased risk of waking up from deep sleep. As such, exaggerated feelings of fatigue can negatively impact alertness and cognitive performance, due to sleep inertia. Study objective Investigating the effect of different durations and composition (in terms of sleep stages) of daytime napping on subjective wellbeing, performance and alertness. Design 24 participants were enrolled in a counter balanced protocol containing four different nap conditions. Sleep was measured using Polysomnography. Subjective wellbeing was measured using Questionnaires and performance was measured using computerized tasks quantifying vigilance, prefrontal functioning and motor functioning Results When comparing subjective sleepiness before and after the naps, participants reported being more fatigued after the nap as compared to before the nap in condition S1, S2 and S2max.

  • The Benefits of Sleep and the Power Nap by Elizabeth Scott, M.S
    The Benefits of Sleep and the Power Nap By Elizabeth Scott, M.S. Why a Power Nap? Facts on Sleep: While small children typically take naps in the afternoon, our culture generally frowns upon mid-day sleep; however, even in those who get enough sleep (but particularly in those who don’t, many people experience a natural decrease in drowsiness in the afternoon, about 8 hours after waking. Research shows that you can make yourself more alert, reduce stress and improve cognitive functioning with a nap. Mid-day sleep or a “power nap, means more patience, less stress, better reaction time, increased learning, more efficiency and better health. Here’s what you need to know about the benefits of sleep and how a power nap can help you. How Much Sleep Do You Need? The body needs 7-8 hours of sleep per day; 6 hours or less triples your risk of a car accident. Interestingly, too much sleep – more than 9 hours- can actually be harmful for your health; recent studies show that those who sleep more than 9 hours a day don’t live as long as their 8-hour counterparts. The Effects of Missed Sleep: Sleep is cumulative; if you lose sleep one day, you feel it the next. If you miss adequate sleep several days in a row, you build up a “sleep deficit”, which impairs the following: • Reaction time • Judgment • Vision • Information processing • Short-term memory • Performance • Motivation • Vigilance • Patience Fatigues people also experience more moodiness, aggressive behaviors, burnout and more stress. The Benefit of a Power Nap: Studies show that 20 minutes of sleep in the afternoon provides more rest than 20 minutes more sleep in the morning ( thought the last two hours of morning sleep have special benefits of their own).

  • There's a Sweet Spot for Making Your Power Nap Count
    There's a Sweet Spot for Making Your Power Nap Count AO Alexandra Ossola Aug 17 2017, 1:00pm https://tonic.vice.com/ Milles Studio/Stocksy Consider this before your next mid-day snooze. It's happened to all of us: Our night selves screw over our morning selves. You stayed up too late having fun or working hard, and the next day you can barely stay awake. All you can think about is a glorious 20-minute rest to embolden you for the rest of your day. But will all those extra ZZZ's really help you concentrate better, or be more creative? The short answer is yes. But you have to be careful how you do it. Sleep varies a lot between individuals. How much you need per night, the best stage of sleep from which you should wake—all of that can vary depending on your genetics, your age, and your personality, says Rebecca Spencer, an associate professor of psychological and brain sciences at the University of Massachusetts, Amherst. Culture can play a role, too; in Spain, for example, the siesta culture means more sleep during the day but less at night. But in America, there's a trend that supersedes these individual differences: Americans are more sleep-deprived than ever. More than a third of us aren't getting enough sleep, according to a 2016 report from the Centers for Disease Control and Prevention. Over time, too little sleep has been associated with an increased risk of a number of chronic health conditions, like obesity, diabetes, heart disease, mood disorders like depression and anxiety, and alcoholism.
